Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.

Performance Expectation

Grade: 
High School (9-12)
Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.

Performance Expectation

Grade: 
High School (9-12)
Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.

Performance Expectation

Grade: 
High School (9-12)
Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.

Performance Expectation

Grade: 
High School (9-12)
Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.

Performance Expectation

Grade: 
High School (9-12)
Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium.*

Performance Expectation

Grade: 
High School (9-12)
Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.

Performance Expectation

Grade: 
High School (9-12)
Develop models to illustrate the changes in the composition of the nucleus of the atom and the energy released during the processes of fission, fusion, and radioactive decay.

Performance Expectation

Grade: 
High School (9-12)
